The arrows shows the direction of rotation of the

tire

Summer and winter tires

When switching between summer and

winter tires, mark the tires to indicate

where they were mounted on the car, e.g.,

LF = left front, RR = right rear

Tires with tread designed to roll in only one

direction are marked with an arrow on the

sidewall.

Incorrectly mounted tires impair the car's

braking properties and ability to force

aside rain, snow and slush.

The tires with the most tread should always

be at the rear (to reduce the risk of skid-

ding).

Contact a Volvo workshop if you are

unsure about the tread depth.

Tire rotation

Your vehicle has no recommended tire rota-
tion. The following information is intended to
help you understand why.

Tread set

As a tire ages and the rubber cures, front and
rear tires set at different angles. Therefore, if
tires are rotated, the tread will eventually set at
an angle that is a compromise. Even if ride,
handling, and road noise may still seem
acceptable, they may not be optimal. Further,
tires that are rotated, but not on a regular basis,
may actually cause more tire noise, faster tire
wear, and unpleasant changes in steering feel
and vehicle handling.
A tire that can fully adapt to its position will
provide better steering feel, lower tire noise,
and better fuel economy.

Braking stability performance

Your vehicle is driven mainly by the front tires,
which will wear faster. This can be beneficial.
Having more tread on the rear tires will help
reduce oversteer. Oversteer is when a vehicle
wants to keep turning because of momentum
and dynamic forces on its suspension.

Suspension wear diagnostics

Every suspension needs periodic inspection
and maintenance. A tire's wear pattern can be

an aid in detecting a suspension problem. Each
tire, if left in place, tells a story about the sus-
pension. Tire rotation, on the other hand, could
make suspension wear harder to detect. Early
detection is very important, because suspen-
sion problems can make tire wear worse.

If you do rotate your tires…

Please follow the tire manufacturer's recom-
mendations, as outlined in the tire manufactur-
ers tire warranty pamphlet.
Your Volvo retailer can also provide guidance
based on your particular driving circumstan-
ces.
